Area Police
Roughly 50 vehicles have been marked with what seems to be human blood in the German city of Hanau in proximity to Frankfurt, according to police.
Cars, walls and mailboxes were marked, in some cases with swastikas, they stated in a statement.
Law enforcement say they were notified late on Wednesday night, when a individual noticed that a car in the Lamboy area of Hanau had been smeared with a reddish-hued substance.
The liquid had been drawn in the pattern of a swastika, they added.
Law enforcement then discovered many other marked vehicles and residential walls in the nearby vicinity.
Swastikas are banned in Germany under legislation prohibiting the public exhibition of Nazi symbols.
Officials say early analysis suggest the fluid was probably blood from a person.
"There is still no clue as to where it came from; officials are currently not cognizant of any physical harm in association with the event," they added.
Municipal representatives said they were trying "to unravel the incident" and have requested to the community for details.
An important representative stated the attack made him without words and required to be resolved promptly.
"This event hits the core of Hanau and reawakens the pain of the right-wing attack in 2020," he wrote on social media, referring to the death of nine victims by a gunman targeting people of immigrant origin in 2020.
